Tried to upgrade to 2.3 on a test wordpress installation. Exporting entries and importing it went ok (but over 4000 entries takes too long so I had to re-do that 4 or 4 times. But again on 2.3 I find the ‘ARRAY’ issue appearing in the admin interace and weblog (standard template)
Compability is going to be less with WordPress and all the version(s) they release. It’s a pain in the ass. and I am not happy about it. I am my own ISP with Bluequartz system on CentOS 4.x and various settings are hard to made or upgrade without breaking the whole back-end admin interface of the Server I run.
